Eric Dumazet 5d4cc87414 net: reorganize "struct sock" fields 
Last major reorg happened in commit 9115e8cd2a ("net: reorganize
struct sock for better data locality")

Since then, many changes have been done.

Before SO_PEEK_OFF support is added to TCP, we need
to move sk_peek_off to a better location.

It is time to make another pass, and add six groups,
without explicit alignment.

- sock_write_rx (following sk_refcnt) read-write fields in rx path.
- sock_read_rx read-mostly fields in rx path.
- sock_read_rxtx read-mostly fields in both rx and tx paths.
- sock_write_rxtx read-write fields in both rx and tx paths.
- sock_write_tx read-write fields in tx paths.
- sock_read_tx read-mostly fields in tx paths.

Results on TCP_RR benchmarks seem to show a gain (4 to 5 %).

It is possible UDP needs a change, because sk_peek_off
shares a cache line with sk_receive_queue.
If this the case, we can exchange roles of sk->sk_receive
and up->reader_queue queues.

After this change, we have the following layout:

struct sock {
	struct sock_common         __sk_common;          /*     0  0x88 */
	/* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */
